Section A of the song covers 0:06 to 0:33 in the original song, and like that your guitar should mostly be providing texture for the synth string lead

Section B is just like Section A, but the string goes into the background and the main melody will be played by you on the guitar

Section C is original. it starts with synth, you're free to improvise alongside, then switches to you playing the melody again

Section D has the length and chord progression of section A/B but is devoid of anything except your solo
